Premiere Pro 25.1 Bug: Vertical Pixel Aspect Ratio is reduced by 1%

It is indeed working fine for me in the latest Beta. Thank you for adressing this.

v25.3 still has the same issue. Pixel ratio sometimes gets shown as 1,0075 (1,0) and interpretting doesnt help. Its simple 1080p mp4 footage from a sony a7s3.

Imported to PR 25.2.1 on Win 10 via Media Browser. Properties there show 1920x1080 (1.0). Added to a UHD sequence, it comes in as 200% (i.e. scaled correctly).

I forgot that I had preferences -> Media set to default Fit to frame, but turned off, it comes on to the UHD sequence as 100%; changed to 200%, correct aspect.

I've suspected on some other issues graphics driver differences PC vs Mac. No idea what is going on here.

sure, here you go.

@Daniel302953428efj,

Thanks for the screenshots. I'm looking for an actual sample file, not too long, that I can download and test.

Sure! Here is a screenshot of a 1080p FX3 clip in a 1080p timeline with a red color matte on the layer below. Same thing in a 2160p timeline btw. I also attached a screenshot of the media file properties for said clip.

edit: on 1080p squence i cant warp stabilize the clip either. I wrote wrong info above cant edit the post. 

I am having the same issue, using MacBook Pro m1 max 32 core from 2021. When i import the same clip to premiere pro 2024 it is okay, when i import the same clip to the newest premiere pro 2025 (dont remember exact number but its up to date) i am getting the same problem as OP.

IMPORTANT: It is only happening when i need to use "scale to frame size", for example, only in 1920x1080 clip using on 3840x2160 sequence, when i import this clip on the 1080p sequence, it is okay. Furthermore, in project window, these clips with issues under video info tab says: 1920 x 1090 (1,0075), pixel square ratio isnt 1.0 as on 4k clips, only in FullHD clips, so strange. Also, i cant even use warp stabilizer on those clips on a 4k sequence because there is a warming poping up saying that i need to match pixel ratio to the sequence, whereas on fullhd sequence its ok. 

@Daniel302953428efj,

Thanks. Can you post a small sample of the problem footage?
